Abstract
A zirconia ceramic material for use in dental applications is provided comprising an yttria-stabilized zirconia material stabilized with 5 mol % yttria to 8 mol % yttria, and methods for making a sintered body from the ceramic material. The zirconia ceramic materials exhibit both enhanced translucency and a flexural strength of at least 300 MPa, or at least 500 MPa, when fully sintered.
